Further, ligaments and nerves of a foot, a knee, an ankle, a waist, a neck, an arm, and a hand or internal organs are exposed to a danger.

Most of the injuries may be caused due to a physical contact among players. However, notwithstanding that there is no peculiar physical contact, an abnormal phenomenon of inner parts of a body due to an immoderate game and a training game of players is not sensed on the basis of a pressure to inner and outer parts of a body, and therefore players may die or become unconscious. When a game is in full swing, players have the maximum stress and tension and reach a physically unbearable condition, and therefore have degraded self-regulation ability, such that they may easily forget their own risk situations. As a result, players may be suddenly collapse during a game to be a vegetable of unconsciousness and even die.

Players themselves need to regulate physical danger or change of players who are in athletics or a couch and a medical staff need to manage players. However, as long as players regulate their own physical problems for themselves and as a result the physical problems of players do not alarm anybody, and therefore players who participate in a real game may not receive help from anybody.

In order to clearly describe the present invention, portions that are not connected with the description will be omitted. Like reference numerals designate like elements throughout the specification. In addition, the detailed description of the widely known technologies will be omitted.

Therefore, since exemplary embodiments stated in the present specification and configurations shown in the accompanying drawings are only exemplary embodiments of the present invention and do not represent the spirit of the present invention, it is to be understood that various equivalents and modifications that may replace exemplary embodiments stated in the present specification and configurations shown in the accompanying drawings at a point in time at which the present invention is filed.

Hereinafter, an apparatus, a system, and a method for managing a player with a guard worn at a player according to an exemplary embodiment of the present invention will be described.

FIG. 1 is a diagram illustrating a configuration of a system for managing a player according to an exemplary embodiment of the present invention.

Referring to FIG. 1 , a system 100 for managing a player according to an exemplary embodiment of the present invention includes a guard 300 worn at a player and an apparatus 200 for managing a player with the guard 300. The system 100 for managing a player may further include an external terminal 400 that may transmit environment information of a stadium to the apparatus 200 for managing a player, a photographing unit 500 photographing a game content of a player and transmitting the photographed game image to the apparatus 200 for managing a player, and a player conservancy terminal 600 carried by a player conservancy.

The guard 300 protects an injured part and relieves a pain of a player due to an external shock while a player is in athletics and is worn while adhering to a skin to protect a body. Here, the inside of the guard 300 adheres to a skin (epidermis and dermis) to easily sense vital information of a player and the guard 300 transmits the sensed vital information to the apparatus 200 for managing a player.

The vital information means information for understanding a body condition of a player wearing the guard 300 and may include at least one of, for example, a blood pressure, a blood flow, a heart rate, electrocardiogram, body temperature, an in vivo nutrient, a total body fluid, a muscle contraction, lactic acid, a nerve, and a ligament.

The apparatus 200 for managing a player according to the exemplary embodiment of the present invention may include a vital information acquisition unit 212, an environment information acquisition unit 214, an activity information acquisition unit 216, and an injury risk extraction unit 218.

Generally, players run 3 to 11 m per second that is activity per high-intensive exercise time. If it is assumed that players run 6 m per second, they run about 21,600 m for 60 minutes and 43,200 m for 120 minutes. Although the heart rate may be different according to an age and a sex of a player, if the intensity is continued for a reference time, players have a heart rate of 220−age=maximum heart rate of 150 to 213. Players do high-intensive exercise activity and have a predetermined recovering time to recover a normal heart rate and then needs to do next activity. When a body is not normally recovered, that is, when players continuously do exercise activity without recovering time, recovering ability may significantly deteriorate or fatigability may be increased, such that players may be highly likely to be injured. Further, although extreme fatigability, a slight ache, an increase in perspiration, nausea, dizziness, shortness of breath, sleeplessness, and anxiety that are a warning sign of a heart attack and an injury may be different according to an age and a sex, there is a need to monitor the warning sign of the heart attack and the injury risk in advance to take a prevention and a measure according to a player condition.

Time when the player condition is normally recovered may be different for each player and a recovering speed may be fast or slow depending on even environmental elements in which a game is performed. The apparatus 200 for managing a player according to the exemplary embodiment of the present invention may use pre-stored vital recovering ability data of a user and a stadium and external environment information that may affect a recovering speed of a player, that is, surface hardness of grass, ground, moisture, a gravitational acceleration of a ball, a fan, noise, temperature, altitude, wind, and vital information and activity information of a player to monitor a change in a player condition, thereby acquiring an injury risk and alarming a player and a player conservancy of the acquired injury risk.

The vital information acquisition unit 212 receives vital information for understanding a player condition from the guard 300.

The environment information acquisition unit 214 receives environment information from at least one external terminal.

The environment information means information which may affect a physical or mental condition of a player. For example, the environment information may include at least one of weather information such as humidity, temperature, a wind volume, a wind direction, and noise in a stadium and stadium information such as altitude, geological features, a grass state of a playground, an air pressure of a ball, and a repulsive force of a ball.

The activity information acquisition unit 216 may acquire activity information such as activity time, an activity distance, and activity mass, etc. of a player from the guard 300 or use the game image information received from the photographing unit 500 to sense a change in position of a player from the received game image to thereby calculate a quantity of motion of players or monitor players' motions, thereby extracting the activity information of players.

The photographing unit 500 may be disposed at a goalpost, a corner flag, and a line in a stadium or outside a stadium to relay a game to photograph a game image for monitoring a position of a player as various angles.

The injury risk extraction unit 218 uses the vital information of a player received by the vital information acquisition unit 212, the environment information received by the environment information acquisition unit 214 that may affect a player, and the activity information of a player acquired by the activity information acquisition unit 216 and uses the vital recovering ability data stored in the vital recovering ability data storage unit 219 to extract the injury risk of a player. The vital recovering ability data may include at least one of data that may be generally applied according to a sex and an age of a player and an athletic event of a player and personal data that are measured during a game history and training that is already done by each player and individually accumulated.

Further, the apparatus 200 for managing a player transmits the calculated risk of injury to the guard 300 that a player wears to allow a player to control his/her own condition for himself/herself or transmits the calculated risk of injury to the player conservancy terminal 600 carried by at least one of a supervisor, a medical staff, a judge, and a coaching staff monitoring a player state and managing a game to smoothly operate the game.

That is, the system 100 for managing a player according to the exemplary embodiment of the present invention integrates the vital information of a player received from the guard 300, the environment information received from at least one external terminal 400, and the activity information of a player extracted from the game image received from the photographing unit 500 to analyze and understand a current body condition and a physical strength condition of a player. Further, the degree of injury risk is calculated on the basis of the pre-stored vital recovering ability data of players such as the past game information, training information, and injury information. The degree of injury risk is the degree that the injury risk of a player is expected or a player's health or life is in danger if a player continues a game.

According to the exemplary embodiment of the present invention, the injury risk extraction unit 218 may integrate vital analysis data, in vivo nutrient content data, environmental element analysis data, operation analysis data, and recoding data of a player to calculate the injury risk of a player in three phases of a normal phase, a warning phase, and a risk phase.

In this case, the vital analysis data may include at least one of an age of a player, a moving distance per hour, a heart rate, a recovering speed, oxygen saturation, a respiration volume, a blood pressure, lactic acid, a discharged amount of sweat, body temperature, in vitro secretion, and pain information as shown in the following Table 1.
